　ロアアーム３０は金属等によって形成された部材である。ロアアーム３０の基端部は、車輪２０に対して車幅方向内側の位置で、フロア部分１２に対して揺れ動き可能に支持される。ロアアーム３０の基端部が揺れ動く際に中心となる軸は、車体１０の前後方向に沿っている。ロアアーム３０の基端部は、車輪２０に対して斜め前方、内側、斜め後方、後方等でフロア部分１２に揺れ動き可能に支持されていてもよい。これらの場合において、ロアアーム３０が揺れ動く際の回転軸は、車体１０の左右方向に沿っていてもよいし、前後方向に沿っていてもよいし、左右方向及び前後方向の両方に対して斜め方向に沿っていてもよい。 The lower arm 30 is a member made of metal or the like. The base end portion of the lower arm 30 is supported so as to be swingable with respect to the floor portion 12 at a position inside the vehicle width direction with respect to the wheel 20. The axis centered when the base end portion of the lower arm 30 swings is along the front-rear direction of the vehicle body 10. The base end portion of the lower arm 30 may be swayably supported by the floor portion 12 diagonally forward, inward, diagonally rearward, rearward, or the like with respect to the wheel 20. In these cases, the axis of rotation when the lower arm 30 swings may be along the left-right direction of the vehicle body 10, along the front-rear direction, or in an oblique direction with respect to both the left-right direction and the front-rear direction. May be along.
　ロアアーム３０の先端部は、フロア部分１２からフェンダーエプロン１６内に向けて（ここでは車幅方向外側に向けて）延びる。ロアアーム３０の先端部には、軸受部３１が設けられている。下側ナックル部２６が軸受部３１を介してロアアーム３０の先端部に回転可能に支持される。軸受部３１による回転軸は、車輪２０がフェンダーエプロン１６内で回転する操舵回転中心軸である。 The tip of the lower arm 30 extends from the floor portion 12 toward the inside of the fender apron 16 (here, toward the outside in the vehicle width direction). A bearing portion 31 is provided at the tip of the lower arm 30. The lower knuckle portion 26 is rotatably supported by the tip portion of the lower arm 30 via the bearing portion 31. The rotation axis by the bearing portion 31 is a steering rotation center axis in which the wheel 20 rotates in the fender apron 16.
　上記したように、ロアアーム３０の基端部がフロア部分１２に対して揺れ動き可能に支持されているため、ロアアーム３０は、車輪２０を、フェンダーエプロン１６内で上下方向に移動可能に支持している。ロアアーム３０によって車輪２０の移動方向が規制された状態で、ダンパ２８が上側ナックル部２５と車体１０との間に介在する。このダンパ２８と当該ダンパ２８に外装されたバネ２７とが、走行時における路面の凹凸による衝撃を吸収する。 As described above, since the base end portion of the lower arm 30 is supported so as to be swingable with respect to the floor portion 12, the lower arm 30 supports the wheel 20 so as to be movable in the vertical direction in the fender apron 16. .. The damper 28 is interposed between the upper knuckle portion 25 and the vehicle body 10 in a state where the moving direction of the wheel 20 is restricted by the lower arm 30. The damper 28 and the spring 27 external to the damper 28 absorb the impact caused by the unevenness of the road surface during traveling.
　アーム部２６ａの先端部にタイロッド３２が連結されている。運転者によるステアリング操舵によってステアリングホイール１８が回転すると、その回転運動が、ステアリングシャフト１８ａ及びラックアンドピニオン機構等の伝達機構１８ｂを介して、車幅方向の動きとしてタイロッド３２に伝達される。タイロッド３２が車幅方向に動くと、下側ナックル部２６が軸受部３１の回転軸を中心として回転することができる。これにより、ステアリング操舵によって、車輪２０が操舵回転中心軸を中心として回転することができる。車輪２０が操舵回転中心軸を中心として回転することによって、車体１０の進行方向が変えられる。 The tie rod 32 is connected to the tip of the arm portion 26a. When the steering wheel 18 is rotated by steering by the driver, the rotational motion is transmitted to the tie rod 32 as movement in the vehicle width direction via the steering shaft 18a and the transmission mechanism 18b such as the rack and pinion mechanism. When the tie rod 32 moves in the vehicle width direction, the lower knuckle portion 26 can rotate about the rotation axis of the bearing portion 31. As a result, the wheels 20 can be rotated around the steering rotation center axis by steering steering. The traveling direction of the vehicle body 10 is changed by rotating the wheels 20 around the steering rotation center axis.

　配線部材５０においてインホイールモータ４２に接続されて固定される端部が第１固定部位５１とされる。第１固定部位５１は配線接続部４３に固定される。第１固定部位５１は凹部４６の底部の位置に固定される。第１固定部位５１において複数の電線５３、５４、５５、５６はシース５７の端部から延出し、ばらけた状態とされている。 The end portion of the wiring member 50 that is connected to and fixed to the in-wheel motor 42 is referred to as the first fixing portion 51. The first fixing portion 51 is fixed to the wiring connection portion 43. The first fixing portion 51 is fixed at the position of the bottom of the recess 46. At the first fixing portion 51, the plurality of electric wires 53, 54, 55, 56 extend from the end of the sheath 57 and are in a disassembled state.
　また、配線部材５０においてインホイールモータ４２に接続される端部の次に車両に固定される部分が第２固定部位５２とされる。第２固定部位５２は配線固定部４５に固定される。第２固定部位５２がケーシング４４のうち凹部４６の開口部を形成する部分に固定される。第２固定部位５２において複数の電線５３、５４、５５、５６はシース５７によってまとめられている。従って、シース５７の端部は、第１固定部位５１と第２固定部位５２との間に位置する。 Further, the portion of the wiring member 50 that is fixed to the vehicle next to the end connected to the in-wheel motor 42 is referred to as the second fixing portion 52. The second fixing portion 52 is fixed to the wiring fixing portion 45. The second fixing portion 52 is fixed to the portion of the casing 44 that forms the opening of the recess 46. In the second fixing portion 52, the plurality of electric wires 53, 54, 55, 56 are grouped by the sheath 57. Therefore, the end of the sheath 57 is located between the first fixing portion 51 and the second fixing portion 52.
　配線部材５０は第１固定部位５１と第２固定部位５２との間でケーシング４４に沿って延びる。そして、配線部材５０は第２固定部位５２を境に、ケーシング４４から離れるように車体側に向けて延びる。この場合、配線部材５０のうちケーシング４４に沿って延びる部分の一方の端部が第１固定部位５１とされ、他方の端部が第２固定部位５２とされる。なお、配線部材５０がケーシング４４に沿って延びる部分とは、ケーシング４４の内部を延びたり、ケーシング４４の表面に沿って延びたりする部分である。 The wiring member 50 extends along the casing 44 between the first fixing portion 51 and the second fixing portion 52. Then, the wiring member 50 extends toward the vehicle body side so as to be separated from the casing 44 with the second fixing portion 52 as a boundary. In this case, one end of the portion of the wiring member 50 extending along the casing 44 is designated as the first fixing portion 51, and the other end is designated as the second fixing portion 52. The portion where the wiring member 50 extends along the casing 44 is a portion which extends inside the casing 44 or extends along the surface of the casing 44.
　第２固定部位５２は蓋部材６０を介して凹部４６の周壁４８に固定されている。従ってここでは配線部材の配索構造４０は蓋部材６０をさらに備える。またフェンダーエプロン１６内において配線部材５０のうち第２固定部位５２よりも車体１０側の一部は、支持部材７０によって支持されている。従ってここでは配線部材の配索構造４０は支持部材７０をさらに備える。 The second fixing portion 52 is fixed to the peripheral wall 48 of the recess 46 via the lid member 60. Therefore, here, the wiring structure 40 of the wiring member further includes a lid member 60. Further, in the fender apron 16, a part of the wiring member 50 on the vehicle body 10 side with respect to the second fixing portion 52 is supported by the support member 70. Therefore, here, the wiring structure 40 of the wiring member further includes a support member 70.
　＜蓋部材＞
　蓋部材６０は第２固定部位５２において配線部材５０の周囲に設けられている。蓋部材６０は凹部４６の開口部を覆う。ここでは蓋部材６０は凹部４６の開口部において周壁４８の内周側に嵌る。蓋部材６０は周壁４８の内周側に嵌っていなくてもよい。例えば、蓋部材は周壁４８の端面よりも外側に位置し凹部４６の開口部を塞いでいてもよい。また例えば、蓋部材の外縁に軸方向に突出する突出部が設けられ、この突出部の内周側に周壁４８が嵌っていてもよい。蓋部材６０は本体６２と外周部６４とを含む。 <Cover member>
The lid member 60 is provided around the wiring member 50 at the second fixing portion 52. The lid member 60 covers the opening of the recess 46. Here, the lid member 60 fits on the inner peripheral side of the peripheral wall 48 at the opening of the recess 46. The lid member 60 does not have to be fitted on the inner peripheral side of the peripheral wall 48. For example, the lid member may be located outside the end surface of the peripheral wall 48 and may close the opening of the recess 46. Further, for example, a protruding portion protruding in the axial direction may be provided on the outer edge of the lid member, and the peripheral wall 48 may be fitted on the inner peripheral side of the protruding portion. The lid member 60 includes a main body 62 and an outer peripheral portion 64.
　本体６２は弾性材料によって形成される。本体６２の形状は如何なる形状であってもよい。ここでは本体６２の外形状は円形状に形成される。本体６２の外形状は凹部４６の横断面形状に応じた形状に形成されるとよい。本体６２には孔６２ｈが形成されている。 The main body 62 is formed of an elastic material. The shape of the main body 62 may be any shape. Here, the outer shape of the main body 62 is formed into a circular shape. The outer shape of the main body 62 may be formed in a shape corresponding to the cross-sectional shape of the recess 46. A hole 62h is formed in the main body 62.
　孔６２ｈは本体６２を貫通する。孔６２ｈは本体６２において凹部４６の底部を向く面とその反対を向く面とを貫通する。配線部材５０は孔６２ｈを通り、蓋部材６０の一方側から他方側へ延びている。孔６２ｈの形状は如何なる形状であってもよい。孔６２ｈは配線部材５０のうち第２固定部位５２の横断面形状に応じた形状に形成されるとよい。ここでは配線部材５０のうちシース５７が設けられた部分が孔６２ｈを通っている。シース５７の外形状が円形状であるため、ここでは孔６２ｈは円形状に形成される。 The hole 62h penetrates the main body 62. The hole 62h penetrates the surface of the main body 62 facing the bottom of the recess 46 and the surface facing the opposite side. The wiring member 50 passes through the hole 62h and extends from one side to the other side of the lid member 60. The shape of the hole 62h may be any shape. The hole 62h may be formed in a shape corresponding to the cross-sectional shape of the second fixing portion 52 in the wiring member 50. Here, the portion of the wiring member 50 provided with the sheath 57 passes through the hole 62h. Since the outer shape of the sheath 57 is circular, the hole 62h is formed in a circular shape here.
　複数の電線５３、５４、５５、５６はシース５７によって１つにまとめられているため、孔６２ｈの数は１つである。複数の電線５３、５４、５５、５６が１つにまとめられていない場合、孔６２ｈの数は１つであってもよいし、複数であってもよい。孔６２ｈの数が複数の場合、複数の孔６２ｈの配置及び複数の孔６２ｈに通される複数の電線５３、５４、５５、５６の配置は、コネクタ５８における複数の電線５３、５４、５５、５６の配置に応じた配置とされていてもよい。 Since the plurality of electric wires 53, 54, 55, 56 are combined into one by the sheath 57, the number of holes 62h is one. When the plurality of electric wires 53, 54, 55, 56 are not combined into one, the number of holes 62h may be one or a plurality. When the number of holes 62h is plural, the arrangement of the plurality of holes 62h and the arrangement of the plurality of electric wires 53, 54, 55, 56 passed through the plurality of holes 62h are such that the arrangement of the plurality of electric wires 53, 54, 55 in the connector 58, It may be arranged according to the arrangement of 56.
　配線部材５０が通される前の孔６２ｈの大きさは如何なる形状であってもよい。配線部材５０が通される前の孔６２ｈの大きさは配線部材５０の大きさ（ここではシース５７の大きさ）と同じかわずかに小さくてもよい。この場合、配線部材５０が通される際、孔６２ｈが広げられるとよい。配線部材５０が通される前の孔６２ｈの大きさは配線部材５０の大きさ（ここではシース５７の大きさ）よりわずかに大きくてもよい。孔６２ｈと配線部材５０との間に止水剤が設けられていてもよい。孔６２ｈの長さ寸法（本体６２の厚み寸法）は如何なる寸法であってもよい。孔６２ｈに配線部材５０を通す観点からは、孔６２ｈはなるべく短い方がよい。孔６２ｈによって配線部材５０を保持する観点からは、孔６２ｈは配線部材５０を保持できる程度の長さがあった方がよい。 The size of the hole 62h before the wiring member 50 is passed may be any shape. The size of the hole 62h before the wiring member 50 is passed may be the same as or slightly smaller than the size of the wiring member 50 (here, the size of the sheath 57). In this case, it is preferable that the hole 62h is widened when the wiring member 50 is passed through. The size of the hole 62h before the wiring member 50 is passed may be slightly larger than the size of the wiring member 50 (here, the size of the sheath 57). A water blocking agent may be provided between the hole 62h and the wiring member 50. The length dimension of the hole 62h (thickness dimension of the main body 62) may be any dimension. From the viewpoint of passing the wiring member 50 through the hole 62h, the hole 62h should be as short as possible. From the viewpoint of holding the wiring member 50 by the hole 62h, the hole 62h should be long enough to hold the wiring member 50.
　本体６２における孔６２ｈの位置は如何なる位置であってもよい。孔６２ｈの位置は配線接続部４３と同軸上の位置に応じた位置に形成されるとよい。配線接続部４３と同軸上の位置とは、図２のようにケーシング４４の正面視において、配線接続部４３と孔６２ｈとが重なる位置である。これにより、第１固定部位５１から第２固定部位５２に向けて配線部材５０がなるべく曲がらずに延びることができる。 The position of the hole 62h in the main body 62 may be any position. The position of the hole 62h may be formed at a position corresponding to the position coaxially with the wiring connection portion 43. The position coaxially with the wiring connection portion 43 is a position where the wiring connection portion 43 and the hole 62h overlap each other in the front view of the casing 44 as shown in FIG. As a result, the wiring member 50 can extend from the first fixing portion 51 toward the second fixing portion 52 without bending as much as possible.
　外周部６４は本体６２の周囲に設けられた部分である。外周部６４はねじ形状部６５を有する。ねじ形状部６５は弾性材料よりも高剛性の材料によって形成されている。ここでは外周部６４の外向き面にねじ形状部６５が設けられている。ねじ形状部６５は周壁４８のねじ形状部４９に締められている。ねじ形状部４９、６５は対応する形状に形成されている。外周部６４は蓋部材６０の軸方向に沿って突出する部分を有し、その突出部の内向き面にねじ形状部が設けられていてもよい。 The outer peripheral portion 64 is a portion provided around the main body 62. The outer peripheral portion 64 has a screw-shaped portion 65. The thread-shaped portion 65 is formed of a material having a higher rigidity than an elastic material. Here, the screw-shaped portion 65 is provided on the outward surface of the outer peripheral portion 64. The screw-shaped portion 65 is fastened to the screw-shaped portion 49 of the peripheral wall 48. The screw-shaped portions 49 and 65 are formed in corresponding shapes. The outer peripheral portion 64 has a portion protruding along the axial direction of the lid member 60, and a screw-shaped portion may be provided on the inward surface of the protruding portion.
　外周部６４におけるねじ形状部６５と本体６２とは回転自在とされるとよい。これによりねじ形状部４９、６５がねじ締めされる際、又はねじ形状部４９、６５のねじ締めが解除される際、本体６２に通された配線部材５０が回転することが抑制される。例えば、外周部６４はねじ形状部６５と本体６２とを回転自在に連結するベアリングを有していてもよい。本体６２の外周側にベアリングが設けられ、ベアリングの外周側にねじ形状部６５が設けられていてもよい。 It is preferable that the screw-shaped portion 65 and the main body 62 on the outer peripheral portion 64 are rotatable. As a result, when the screw-shaped portions 49 and 65 are screwed, or when the screw-shaped portions 49 and 65 are unscrewed, the wiring member 50 passed through the main body 62 is suppressed from rotating. For example, the outer peripheral portion 64 may have a bearing that rotatably connects the screw-shaped portion 65 and the main body 62. A bearing may be provided on the outer peripheral side of the main body 62, and a screw-shaped portion 65 may be provided on the outer peripheral side of the bearing.
　ねじ形状部４９、６５がねじ締めされた状態で、本体６２はねじ形状部６５に対して回転することが抑制されるとよい。これにより、ねじ形状部４９、６５がねじ締めされた状態で、本体６２に通された配線部材５０が回転することが抑制される。例えば、周壁４８においてねじ形状部４９よりも底部側の部分が内周側に突出し、段差Ｓが設けられている。ねじ形状部４９、６５がねじ締めされた状態で、周壁４８の段差部分と本体６２の外縁とが密着する。これにより、ねじ形状部４９、６５がねじ締めされた状態で、周壁４８と本体６２との摩擦によってねじ形状部６５に対する本体６２の回転が抑制される。 It is preferable that the main body 62 is suppressed from rotating with respect to the screw-shaped portion 65 while the screw-shaped portions 49 and 65 are screw-tightened. As a result, the wiring member 50 passed through the main body 62 is suppressed from rotating while the screw-shaped portions 49 and 65 are screwed. For example, in the peripheral wall 48, a portion on the bottom side of the screw-shaped portion 49 projects toward the inner peripheral side, and a step S is provided. With the screw-shaped portions 49 and 65 screwed, the stepped portion of the peripheral wall 48 and the outer edge of the main body 62 are in close contact with each other. As a result, the rotation of the main body 62 with respect to the screw-shaped portion 65 is suppressed by the friction between the peripheral wall 48 and the main body 62 in the state where the screw-shaped portions 49 and 65 are screwed.
　ここでは、蓋部材６０によって凹部４６の内部が止水されている。これについて、図４を参照しつつ詳述する。図４は、図３の領域Ａの拡大図である。 Here, the inside of the recess 46 is stopped by the lid member 60. This will be described in detail with reference to FIG. FIG. 4 is an enlarged view of the region A of FIG.
　具体的には、蓋部材６０における本体６２は、ケーシング４４、外周部６４及び配線部材５０それぞれと密着している。これにより、本体６２とケーシング４４、外周部６４及び配線部材５０それぞれとの間からの水の浸入を抑制している。ここでは本体６２は、配線部材５０の径方向において外周部６４と配線部材５０とに密着し、配線部材５０の長手方向において外周部６４とケーシング４４とに密着している。この際、本体６２にはケーシング４４、外周部６４及び配線部材５０それぞれと接する部分にリップが設けられている。かかるリップとして、図４に示す例では、第１リップ６３ａ、第２リップ６３ｂ、６３ｃ、及び第３リップ６３ｄが設けられている。 Specifically, the main body 62 of the lid member 60 is in close contact with the casing 44, the outer peripheral portion 64, and the wiring member 50, respectively. As a result, the ingress of water from between the main body 62 and the casing 44, the outer peripheral portion 64, and the wiring member 50 is suppressed. Here, the main body 62 is in close contact with the outer peripheral portion 64 and the wiring member 50 in the radial direction of the wiring member 50, and is in close contact with the outer peripheral portion 64 and the casing 44 in the longitudinal direction of the wiring member 50. At this time, the main body 62 is provided with a lip at a portion in contact with each of the casing 44, the outer peripheral portion 64, and the wiring member 50. As such lips, in the example shown in FIG. 4, the first lip 63a, the second lip 63b, 63c, and the third lip 63d are provided.
　第１リップ６３ａは、本体６２のうちケーシング４４と接触する部分に設けられている。より詳細には、ケーシング４４のうち周壁４８の段差Ｓが環状に形成される。本体６２のうち軸方向を向く端面のうち外周縁部が段差Ｓに接する。本体６２における当該外周縁部に第１リップ６３ａが環状に設けられる。第１リップ６３ａは段差Ｓと軸方向に並ぶ。環状の第１リップ６３ａが全周にわたって段差Ｓに接する。第１リップ６３ａは、ねじ形状部４９、６５がねじ締めされた状態で、段差Ｓ及び外周部６４によって軸方向に挟まれて押圧されているとよい。 The first lip 63a is provided in a portion of the main body 62 that comes into contact with the casing 44. More specifically, the step S of the peripheral wall 48 of the casing 44 is formed in an annular shape. The outer peripheral edge of the end face of the main body 62 facing the axial direction is in contact with the step S. The first lip 63a is provided in an annular shape on the outer peripheral edge portion of the main body 62. The first lip 63a is aligned with the step S in the axial direction. The annular first lip 63a touches the step S over the entire circumference. The first lip 63a may be pressed by being sandwiched in the axial direction by the step S and the outer peripheral portion 64 in a state where the screw-shaped portions 49 and 65 are screwed.
　第２リップ６３ｂ、６３ｃは、本体６２のうち外周部６４と接触する部分に設けられている。より詳細には、第２リップ６３ｂは、本体６２のうち第１リップ６３ａが設けられる端面の裏面に環状に設けられる。図４に示す例では、第２リップ６３ｂは第１リップ６３ａの真裏に設けられているが、第１リップ６３ａ及び第２リップ６３ｂは径方向に沿って内外に分かれて設けられていてもよい。第２リップ６３ｂは外周部６４と軸方向に並ぶ。環状の第２リップ６３ｂが全周にわたって、外周部６４の環状の端面に接する。第２リップ６３ｂは、ねじ形状部４９、６５がねじ締めされた状態で、段差Ｓ及び外周部６４によって軸方向に挟まれて押圧されているとよい。 The second lips 63b and 63c are provided on the portion of the main body 62 that comes into contact with the outer peripheral portion 64. More specifically, the second lip 63b is provided in an annular shape on the back surface of the end surface of the main body 62 where the first lip 63a is provided. In the example shown in FIG. 4, the second lip 63b is provided directly behind the first lip 63a, but the first lip 63a and the second lip 63b may be provided separately inside and outside along the radial direction. .. The second lip 63b is axially aligned with the outer peripheral portion 64. The annular second lip 63b touches the annular end face of the outer peripheral portion 64 over the entire circumference. The second lip 63b may be pressed by being sandwiched in the axial direction by the step S and the outer peripheral portion 64 in a state where the screw-shaped portions 49 and 65 are screwed.
　また第２リップ６３ｃは、本体６２のうち外周部６４の内周面に対向する外周面に全周にわたって環状に設けられている。図４に示す例では、第２リップ６３ｃは本体６２の外周面において軸方向に離れて２つ設けられている。第２リップ６３ｃは外周部６４と径方向に並ぶ。環状の第２リップ６３ｃが全周にわたって、外周部６４の内周面に接する。 Further, the second lip 63c is provided in an annular shape on the outer peripheral surface of the main body 62 facing the inner peripheral surface of the outer peripheral portion 64 over the entire circumference. In the example shown in FIG. 4, two second lips 63c are provided on the outer peripheral surface of the main body 62 apart from each other in the axial direction. The second lip 63c is radially aligned with the outer peripheral portion 64. The annular second lip 63c touches the inner peripheral surface of the outer peripheral portion 64 over the entire circumference.
　第３リップ６３ｄは、本体６２のうち配線部材５０と接触する部分に設けられている。より詳細には、第３リップ６３ｄは、本体６２のうち孔６２ｈの内周面に全周にわたって環状に設けられる。図４に示す例では、第３リップ６３ｄは孔６２ｈの内周面において軸方向に離れて２つ設けられている。第３リップ６３ｄは配線部材５０のシース５７と径方向に並ぶ。環状の第３リップ６３ｄが全周にわたって、シース５７の外周面に接する。 The third lip 63d is provided in a portion of the main body 62 that comes into contact with the wiring member 50. More specifically, the third lip 63d is provided in an annular shape on the inner peripheral surface of the hole 62h in the main body 62 over the entire circumference. In the example shown in FIG. 4, two third lips 63d are provided on the inner peripheral surface of the hole 62h apart from each other in the axial direction. The third lip 63d is radially aligned with the sheath 57 of the wiring member 50. The annular third lip 63d touches the outer peripheral surface of the sheath 57 over the entire circumference.
　もっとも、蓋部材６０によって凹部４６の内部が止水されている必要はない。また、蓋部材６０によって凹部４６の内部が止水されている場合でも、その構造は上記したものに限られない。例えば、図４に示す例では、第１リップ６３ａ及び第２リップ６３ｂが１つずつ設けられ、第２リップ６３ｃ及び第３リップ６３ｄが２つずつ設けられているが、各リップの数は、これに限られず、適宜設定可能である。また図４に示す例では、２種類の第２リップ６３ｂ、６３ｃが設けられていたが、第２リップ６３ｂと第２リップ６３ｃとのうちいずれかは省略されてもよい。また図４に示す例では、蓋部材６０は、ねじ形状部４９、６５がねじ締めされてケーシング４４に取付けられるものであったが、蓋部材はケーシング４４に圧入されるものであってもよい。 However, it is not necessary that the inside of the recess 46 is stopped by the lid member 60. Further, even when the inside of the recess 46 is stopped by the lid member 60, the structure is not limited to that described above. For example, in the example shown in FIG. 4, the first lip 63a and the second lip 63b are provided one by one, and the second lip 63c and the third lip 63d are provided two by two, but the number of each lip is different. Not limited to this, it can be set as appropriate. Further, in the example shown in FIG. 4, two types of second lips 63b and 63c are provided, but any one of the second lip 63b and the second lip 63c may be omitted. Further, in the example shown in FIG. 4, the lid member 60 has screw-shaped portions 49 and 65 screwed and attached to the casing 44, but the lid member may be press-fitted into the casing 44. ..
　さらに、蓋部材６０はオイルシール性を有していてもよい。例えば、凹部４６の内部にオイルが設けられ、当該オイルが凹部４６から漏れることを蓋部材６０が抑制するものであってもよい。かかるオイルシール性を有する蓋部材の構成としては、特に限定されるものではないが、例えば、蓋部材は、第３リップ６３ｄの外側に第３リップ６３ｄを配線部材５０に向けて付勢する付勢部材を含んでいてもよい。この場合、本体６２に付勢部材が装着される装着部が設けられると良い。かかる付勢部材は、例えば、コイルバネ等のばね部材が環状に形成されたものであってもよい。 Further, the lid member 60 may have an oil seal property. For example, oil may be provided inside the recess 46, and the lid member 60 may prevent the oil from leaking from the recess 46. The configuration of the lid member having such oil-sealing property is not particularly limited, but for example, the lid member urges the third lip 63d to the outside of the third lip 63d toward the wiring member 50. It may include a force member. In this case, it is preferable that the main body 62 is provided with a mounting portion on which the urging member is mounted. The urging member may be, for example, a spring member such as a coil spring formed in an annular shape.
　蓋部材６０は配線部材５０とは別に成形された部材であり、後から配線部材５０に装着される。 The lid member 60 is a member molded separately from the wiring member 50, and is later attached to the wiring member 50.
　＜支持部材７０＞
　図１に示す例では、支持部材７０は配線部材５０に取付けられる。支持部材７０は上側ナックル部２５に支持されている。例えば支持部材７０はブラケットである。ブラケットは取付対象にねじ止めされる。 <Support member 70>
In the example shown in FIG. 1, the support member 70 is attached to the wiring member 50. The support member 70 is supported by the upper knuckle portion 25. For example, the support member 70 is a bracket. The bracket is screwed to the mounting target.
　もっとも、支持部材７０は、配線部材５０のうち第２固定部位５２と車体側機器８０との間を上記配索形態で支持するものであればよく、そのための構成は特に限定されない。支持部材は、単一の支持部材であってもよいし、複数の支持部分を含んでもよい。また支持部材は、車体１０側に支持されていてもよいし、車輪２０側に支持されていてもよい。ここで、支持部材が車体１０側に支持されるとは、操舵回転中心軸を中心として車輪２０が回転しても回転しない部分に支持されていることをいう。例えば、支持部材が車体１０に支持されている場合のほか、上記ダンパ２８又はロアアーム３０に支持されている場合である。また、支持部材７０が車輪２０側に支持されるとは、操舵回転中心軸を中心として車輪２０が回転するとこれに追随して回転する部分に支持されていることをいう。例えば、支持部材７０が上記上側ナックル部２５又は下側ナックル部２６に支持されている場合である。 However, the support member 70 may be any wiring member 50 that supports the wiring member 50 between the second fixing portion 52 and the vehicle body side device 80 in the above-mentioned wiring form, and the configuration for that purpose is not particularly limited. The support member may be a single support member or may include a plurality of support portions. Further, the support member may be supported on the vehicle body 10 side or may be supported on the wheel 20 side. Here, the fact that the support member is supported on the vehicle body 10 side means that the support member is supported by a portion that does not rotate even if the wheel 20 rotates around the steering rotation center axis. For example, in addition to the case where the support member is supported by the vehicle body 10, the case is the case where the support member is supported by the damper 28 or the lower arm 30. Further, the support member 70 being supported on the wheel 20 side means that the support member 70 is supported by a portion that rotates following the wheel 20 when the wheel 20 rotates about the steering rotation center axis. For example, the support member 70 is supported by the upper knuckle portion 25 or the lower knuckle portion 26.
　蓋部材６０及び支持部材７０の一方又は両方は、車両に取付けられる前に配線部材５０に予め取付けられていると良い。配線部材５０に蓋部材６０及び支持部材７０の一方又は両方が予め取付けられたものは配線モジュールととらえることもできる。配線部材５０に蓋部材６０及び支持部材７０の両方が予め取付けられた配線モジュールにおいて、インホイールモータ４２に接続される端部側から蓋部材６０、支持部材７０の順に設けられる。 It is preferable that one or both of the lid member 60 and the support member 70 are pre-attached to the wiring member 50 before being attached to the vehicle. A wiring module to which one or both of the lid member 60 and the support member 70 are preliminarily attached to the wiring member 50 can also be regarded as a wiring module. In the wiring module in which both the lid member 60 and the support member 70 are previously attached to the wiring member 50, the lid member 60 and the support member 70 are provided in this order from the end side connected to the in-wheel motor 42.

　以上のように構成された配線部材の配索構造４０によると、ケーシング４４の配線固定部４５に第２固定部位５２が固定されることによって、インホイールモータユニット４１の周辺に配置される部品に第２固定部位５２を固定する必要がなくなる。これにより、インホイールモータユニット４１に接続される電線５３、５４、５５、５６の経路の自由度を高めることが可能となる。より詳細には、配線部材５０の端部にかかる力を小さくするため、端部の次の固定部位の位置は端部近く（例えば、端部を基準にＸｍｍ以内の位置。Ｘは例えば１００から３００のいずれかの値。）に設定されることがある。この範囲で端部の次の固定部位の位置がインホイールモータ４２近くの周辺部品に設定される場合、その固定位置が限定されることによって、配線部材５０の経路の自由度が低くなる恐れがある。これに対してここでは、第２固定部位５２がケーシング４４の配線固定部４５に固定されることによって、第２固定部位５２よりも車体側機器８０の経路の自由度が高くなる。また支持部材７０の取付けられる位置の自由度も高くなる。 <Effects of Embodiment 1>
According to the wiring member wiring structure 40 configured as described above, the second fixing portion 52 is fixed to the wiring fixing portion 45 of the casing 44, so that the component is arranged around the in-wheel motor unit 41. It is no longer necessary to fix the second fixing portion 52. This makes it possible to increase the degree of freedom of the paths of the electric wires 53, 54, 55, 56 connected to the in-wheel motor unit 41. More specifically, in order to reduce the force applied to the end of the wiring member 50, the position of the next fixing portion of the end is near the end (for example, a position within X mm with respect to the end. X is, for example, from 100. It may be set to any value of 300.). When the position of the next fixing portion at the end is set in the peripheral component near the in-wheel motor 42 in this range, the degree of freedom of the path of the wiring member 50 may be lowered due to the limitation of the fixing position. be. On the other hand, here, by fixing the second fixing portion 52 to the wiring fixing portion 45 of the casing 44, the degree of freedom of the path of the vehicle body side device 80 is higher than that of the second fixing portion 52. In addition, the degree of freedom in the position where the support member 70 is attached is increased.
　また、第１固定部位５１が凹部４６の底部の位置に固定され、第２固定部位５２が凹部４６の開口部の位置に固定される。これにより、第１固定部位５１から第２固定部位５２までの間において配線部材５０がなるべく曲がらずに固定されることができる。 Further, the first fixing portion 51 is fixed at the position of the bottom of the recess 46, and the second fixing portion 52 is fixed at the position of the opening of the recess 46. As a result, the wiring member 50 can be fixed between the first fixing portion 51 and the second fixing portion 52 without bending as much as possible.
　また、ケーシング４４は凹部４６の開口部の周縁に設けられた放熱フィン４７を含む。これにより、放熱フィン４７が設けられるスペースを利用して、凹部４６を設けることができる。放熱フィン４７が配線固定部４５の一部を構成している。ケーシング４４のうち放熱フィン４７が設けられることによって突出する部分に凹部４６が形成される。これにより、凹部４６を形成するためにケーシング４４の寸法が大きくなることを抑制できる。 Further, the casing 44 includes a heat radiation fin 47 provided on the peripheral edge of the opening of the recess 46. As a result, the recess 46 can be provided by utilizing the space in which the heat radiation fins 47 are provided. The heat radiation fin 47 constitutes a part of the wiring fixing portion 45. A recess 46 is formed in a protruding portion of the casing 44 by providing the heat radiation fins 47. As a result, it is possible to prevent the size of the casing 44 from becoming large due to the formation of the recess 46.
　また、配線部材５０は第２固定部位５２において配線部材５０の周囲に設けられて凹部４６の開口部に取付けられる蓋部材６０をさらに備える。これにより、蓋部材６０を介して第２固定部位５２を簡易にケーシング４４に取り付けることができる。 Further, the wiring member 50 further includes a lid member 60 provided around the wiring member 50 at the second fixing portion 52 and attached to the opening of the recess 46. As a result, the second fixing portion 52 can be easily attached to the casing 44 via the lid member 60.
　また、蓋部材６０の本体６２が弾性材料によって形成されているため電線５３、５４、５５、５６に密着でき、電線５３、５４、５５、５６のがたつきを抑制できる。また、ねじ形状に形成された蓋部材６０の外周部６４によって蓋部材６０が簡易にケーシング４４に取り付けられる。 Further, since the main body 62 of the lid member 60 is formed of an elastic material, it can be in close contact with the electric wires 53, 54, 55, 56, and the rattling of the electric wires 53, 54, 55, 56 can be suppressed. Further, the lid member 60 is easily attached to the casing 44 by the outer peripheral portion 64 of the lid member 60 formed in a screw shape.
　また、凹部４６の周壁４８及び蓋部材６０は凹部４６の内部を止水している。具体的には、本体６２は、ケーシング４４、外周部６４及び配線部材５０それぞれと密着している。これにより、凹部４６内部を止水する簡易な止水構造が設けられる。また、本体６２にはケーシング４４、外周部６４及び配線部材５０それぞれと接する部分に、第１リップ６３ａ、第２リップ６３ｂ、６３ｃ、及び第３リップ６３ｄが設けられている。これにより、凹部４６内部の止水性が高まる。 Further, the peripheral wall 48 of the recess 46 and the lid member 60 stop water inside the recess 46. Specifically, the main body 62 is in close contact with each of the casing 44, the outer peripheral portion 64, and the wiring member 50. As a result, a simple water-stopping structure for stopping the water inside the recess 46 is provided. Further, the main body 62 is provided with a first lip 63a, a second lip 63b, 63c, and a third lip 63d at a portion in contact with each of the casing 44, the outer peripheral portion 64, and the wiring member 50. As a result, the water blocking property inside the recess 46 is enhanced.
　また第１固定部位５１と第２固定部位５２との間にシース５７の端部が位置している。これにより、第２固定部位５２をケーシング４４に取り付ける際の複数の電線５３、５４、５５、５６の取扱いが容易となる。 Further, the end portion of the sheath 57 is located between the first fixing portion 51 and the second fixing portion 52. This facilitates the handling of the plurality of electric wires 53, 54, 55, 56 when the second fixing portion 52 is attached to the casing 44.
　［変形例］
　これまでケーシング４４に凹部４６が形成されるものとして説明されたが、このことは必須の構成ではない。例えば、ケーシングにおいて放熱フィンが形成されない側面に配線接続部が位置していてもよい。また第１固定部位５１と第２固定部位５２との間において配線部材５０が曲げて配索されていてもよい。 [Modification example]
Although it has been described so far that the recess 46 is formed in the casing 44, this is not an essential configuration. For example, the wiring connection portion may be located on the side surface of the casing where the heat radiation fins are not formed. Further, the wiring member 50 may be bent and arranged between the first fixing portion 51 and the second fixing portion 52.
　またこれまで凹部４６における開口部の周縁に放熱フィン４７が設けられているものとして説明されたが、このことは必須の構成ではない。ケーシングにおいて放熱フィン４７の設けられない部分に凹部４６が形成されていてもよい。 Although it has been described so far that the heat radiation fin 47 is provided on the peripheral edge of the opening in the recess 46, this is not an essential configuration. A recess 46 may be formed in a portion of the casing where the heat radiation fin 47 is not provided.
　またこれまで蓋部材６０によって第２固定部位５２が配線固定部４５に固定されるものとして説明されたが、このことは必須の構成ではない。例えば、ブラケットなど、蓋部材６０以外の部品によって第２固定部位５２が配線固定部４５に固定されていてもよい。また配線固定部４５がクリップ状などの配線部材５０を直接支持可能な形状に形成されるなどして、第２固定部位５２が直接ケーシング４４に固定されていてもよい。 Although it has been described so far that the second fixing portion 52 is fixed to the wiring fixing portion 45 by the lid member 60, this is not an essential configuration. For example, the second fixing portion 52 may be fixed to the wiring fixing portion 45 by a component other than the lid member 60 such as a bracket. Further, the second fixing portion 52 may be directly fixed to the casing 44 by forming the wiring fixing portion 45 in a shape such as a clip shape that can directly support the wiring member 50.
　またこれまで蓋部材６０が弾性材料による本体６２と本体６２よりも高剛性の外周部６４とを含むものとして説明されたが、このことは必須の構成ではない。例えば、蓋部材において、外周部６４が省略されてもよい。この場合、蓋部材が凹部４６の開口部に圧入されてもよい。また例えば、蓋部材と凹部４６とはねじ形状部４９、６５とは別のねじによって、蓋部材が凹部４６に取付けられていてもよい。この際、凹部の周壁の外側にねじ受が設けられ、外周部のうちねじ受に対応する位置にねじ孔が設けられていてもよい。また例えば、蓋部材は配線部材５０をインサート物としてインサートモールド成形されたインサートモールド成形体であってもよい。 Further, the lid member 60 has been described so far as including a main body 62 made of an elastic material and an outer peripheral portion 64 having a higher rigidity than the main body 62, but this is not an essential configuration. For example, in the lid member, the outer peripheral portion 64 may be omitted. In this case, the lid member may be press-fitted into the opening of the recess 46. Further, for example, the lid member and the recess 46 may be attached to the recess 46 by a screw different from the screw-shaped portions 49 and 65. At this time, a screw receiver may be provided on the outside of the peripheral wall of the recess, and a screw hole may be provided at a position corresponding to the screw receiver in the outer peripheral portion. Further, for example, the lid member may be an insert-molded body formed by insert-molding the wiring member 50 as an insert.
　またこれまで複数の電線５３、５４、５５、５６がシース５７によって１つにまとめられているものとして説明されたが、このことは必須の構成ではない。例えば、複数の電線５３、５４、５５、５６は１つにまとめられていなくてもよい。また例えば、複数の電線５３、５４、５５、５６をまとめる部材は、シース５７以外の保護部材であってもよい。かかる保護部材は、例えば、コルゲートチューブであってもよいし、螺旋巻された粘着テープであってもよいし、樹脂又は金属チューブであってもよい。また複数の電線５３、５４、５５、５６は、その長手方向全体に亘って１つにまとめられている必要はない。例えば、上記シース５７が省略され、複数の電線５３、５４、５５、５６が、配線部材５０を一定位置に支持する蓋部材６０、ブラケットなどによって１つにまとめられていてもよい。ここでのブラケットは、支持部材７０であってもよい。 Although it has been explained so far that a plurality of electric wires 53, 54, 55, 56 are combined into one by a sheath 57, this is not an essential configuration. For example, the plurality of electric wires 53, 54, 55, 56 may not be combined into one. Further, for example, the member that bundles the plurality of electric wires 53, 54, 55, 56 may be a protective member other than the sheath 57. The protective member may be, for example, a corrugated tube, a spirally wound adhesive tape, or a resin or metal tube. Further, the plurality of electric wires 53, 54, 55, 56 do not need to be combined into one over the entire longitudinal direction thereof. For example, the sheath 57 may be omitted, and the plurality of electric wires 53, 54, 55, 56 may be combined into one by a lid member 60, a bracket, or the like that supports the wiring member 50 at a fixed position. The bracket here may be a support member 70.
　また配線部材５０はインホイールモータユニット４１用の電線５３、５４、５５、５６以外の配線を含んでいてもよい。かかる配線は、インホイールモータユニット４１の周辺に配置される周辺機器に接続される。かかる周辺機器としては、例えば、センサ、電動ブレーキ等であることが想定される。例えば、センサは、車輪２０の回転速度を検出するセンサであってもよいし、インホイールモータ４２等の温度を検知する温度センサであってもよい。電動ブレーキは、自動車の駐停車時に使用される電動パーキングブレーキであってもよいし、自動車の走行時に使用されるブレーキであってもよい。 Further, the wiring member 50 may include wiring other than the electric wires 53, 54, 55, 56 for the in-wheel motor unit 41. Such wiring is connected to peripheral devices arranged around the in-wheel motor unit 41. Such peripheral devices are assumed to be, for example, sensors, electric brakes, and the like. For example, the sensor may be a sensor that detects the rotation speed of the wheel 20, or may be a temperature sensor that detects the temperature of the in-wheel motor 42 or the like. The electric brake may be an electric parking brake used when the vehicle is parked or stopped, or may be a brake used when the vehicle is running.
　これらの周辺機器と周辺機器用の配線との接続部は、電線５３、５４、５５、５６とインホイールモータ４２との接続部と同じ位置に設けられてもよいし、異なる位置に設けられてもよい。周辺機器と周辺機器用の配線との接続部が電線５３、５４、５５、５６とインホイールモータ４２との接続部と異なる位置に設けられる場合、電線５３、５４、５５、５６と周辺機器用の配線とは、蓋部材６０よりも車体側機器８０側で分岐していてもよい。 The connection portion between these peripheral devices and the wiring for the peripheral device may be provided at the same position as the connection portion between the electric wires 53, 54, 55, 56 and the in-wheel motor 42, or may be provided at different positions. May be good. When the connection portion between the peripheral device and the wiring for the peripheral device is provided at a position different from the connection portion between the electric wires 53, 54, 55, 56 and the in-wheel motor 42, the electric wires 53, 54, 55, 56 and the peripheral device are provided. The wiring may be branched on the vehicle body side device 80 side rather than the lid member 60.
　周辺機器用の配線によって周辺機器と接続される車体側機器は、周辺機器との間で信号を送受したり、電力を供給したりする機器であればよい。例えば、車体側機器は、センサからの信号を受信したり、上記電動ブレーキを制御したりするＥＣＵ（Electronic Control Unit）としての機能を含むものであってもよい。車体側機器は、車体１０内に設けられてもよいし、車体１０外に設けられてもよい。 The vehicle body side device connected to the peripheral device by wiring for the peripheral device may be a device that sends / receives signals to / from the peripheral device and supplies electric power. For example, the vehicle body side device may include a function as an ECU (Electronic Control Unit) that receives a signal from a sensor and controls the electric brake. The vehicle body side device may be provided inside the vehicle body 10 or may be provided outside the vehicle body 10.
